Inventor: SHIBATA YUJI
IPC: B05D1/36
Filed: 1994-11-04
Abstract: PURPOSE: To suppress bleeding of a plasticizer by using a sealing composition, which is a vinyl chloride-based plastisol composition consisting of vinyl chloride resin and a plasticizer as main agents and containing a filler and using a substance whose surface tension is a specified value for the plasticizer. CONSTITUTION: In a powder paint coating method involving applying a powder paint to a joining part, etc., of a steel sheet to be coated after applying a sealing composition, which is a vinyl chloride-based plastisol composition containing vinyl chloride resin and a plasticizer as main agents and then baking and curing the paint, a plasticizer e.g. BBP, etc., having 39-46dyn/cm<2> surface tension is used for the plastisol. The mixing ratio of the plasticizer is preferably 13-19wt.% of the whole composition. Consequently, compatibility of the plasticizer to the powder paint is made excellent and the plasticizer bled out of the sealing composition at the time of baking and curing is absorbed in the powder paint and the plasticizer is thus effectively prevented from bleeding out of the surface of the powder paint coating.

Title: Optical measuring apparatus
Inventor: TANAKA HIROKAZU
IPC: G01B11/00
Filed: 1989-10-20
Abstract: PURPOSE:To decrease measuring errors by splitting the light from one light source into two light beams having the different properties, changing the lengths of the light paths of the split light beams, projecting the light beams on a material to be measured, transducing the reflected lights from the material to be measured into the electric signals, and comparing and processing the two electric signals. CONSTITUTION:The light from a light source 21 is split through a polarization beam splitter 22 in accordance with polarization components P and S. Namely, the light having the component P is reflected with the splitter 22 and projected on a material to be measured 26. The light having the component S are transmitted through the splitter 22. Then, the reflection is repeated with total reflection mirrors 23 - 25. The light is transmitted through the splitter 22 again and projected on the material to be measured 26. As a result, the distance from the light source 21 to the material to be measured 26 for the light having the component S is longer than the distance for the light having the component P by 2d1 + 2D2. When the reflectivity of the material to be measured 26 is made to be K and the illuminances of the lights having the components P and S are made to be EP and ES, the luminances of the material to be measured 26 have the values corresponding to KDP and KES. When the luminances of the material to be measured 26 are made to be BP and BS, BP/BSinfinity EP/ES is obtained. The distance D to the material to be measured 26 can be computed by measuring the luminances BP and BS regardless of the reflectivity K of the material to be measured 26.

Title: Die bonding device
Inventor: KOBAYASHI HIROAKI
IPC: H01L21/52
Filed: 1987-10-27
Abstract: PURPOSE:To prevent cutout and crack from being produced on a semiconductor die and to optimize production of a number of products by detection contact between the bonding surface of a semiconductor lead frame and the lower surface of a semiconductor die, by setting ponding applied pressure according to the size of the die, and by applying a set pressure to the die being based on the detection result. CONSTITUTION:The lower surface of a semiconductor die 14 which was absorbed a collet 2 comes into contact with the upper surface of a paste 19 which was applied to a lead frame 13. Then, when an arm 4 lowers itself, the contact between a gap sensor 24 and a stopper 9 is released, thus resulting in stop by the OFF signal. At this time, when a motor 22 is allowed to rotate, a collet head 26 lowers itself along a guide lower axis 4b at the tip of the arm 4 and compression force operates on a spring 20. The reaction of this compression force allows pressure to be applied to the lead frame 13 through a collet 12 and bonding to be performed. The applied pressure at this time is determined by the lowering stroke of the head 26. Thus, if the applied pressure is set previously depending on the type and size of the die 14 and the rotary angle of a motor 22 is controlled being based on this setting pressure, the set bonding pressure is applied to the die 14.
